The gauge face shows the unit in psi (also see product details), while the temp-pressure mapping appears to be F-psig.** A: PSIG only. When disconnected the gauges read zero. The P-T chart for R-134a is fairly accurate to within around 3 degrees F, as far as I can tell, which means it is definitely PSIG/TempF. **Q: Is this fahrenheit? i do not want celsius? the pictures show f but the third bullet point on the description says celsius? what is the truth?** A: These have Fahrenheit scale on them. **Q: Under what circumstances should the pins (as shown in D, similar to tire valve pins) be unscrewed from the ends of hoses using the red tool?** A: I would say these are extra valve cores in case one goes bad **Q: Are these low loss fittings?** A: If you buy this product, you will get: 1pc 3-way HAVC freon gauge (1/4" male), 3pc hoses (1/4" female), 2pc quick couplers (1/4" male), 1pc ACME adapter (1/4" Male to 1/2" Female), and 1pc can tap (piercing-style) (1/4" male). They are of good quality. If you need any further assistance, please feel free to contact our customer support.

It did have a couple of issues. The yellow line would not stay tight at the manifold, and occasionally would start to leak, and I would have to tighten it again. This only happened twice, when recharging a system, it was fine when pulling vacuum for a leak test. The other issue is that it doesn't come with an fitting for self sealing cans, and the pierce fitting doesn't thread on to the adapter that I bought very well. It damaged some of the threads, and sits crooked by the time it's fully threaded on. It also opened the valve on one can before it was threaded on all the way, but I don't know if that's an issue with the adapter or the pierce fitting in this kit. ## Frequently Bought Together - Orion Motor Tech AC Gauge Set with Self Sealing & Puncturing R134A Can Tap, AC Gauges for R134a R12 R22 R502 Refrigerant, Car AC Gauge Set with 5FT Hoses Adapter Adjustable Couplers, Freon Charge Kit - Orion Motor Tech Vacuum Pump, 3.5 cfm 1/4 hp HVAC Single Stage Vacuum Pump for R12 R22 R134a R410a R502, Auto AC Vacuum Pump Kit for Automotive Air Conditioner Resin Degassing & More, Oil Included --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/124255794-omt-3-way-ac-gauges-for-r134a-r12-r22-r502](https://www.desertcart.jp/products/124255794-omt-3-way-ac-gauges-for-r134a-r12-r22-r502) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-27*
